It replaces OEM part numbers DR202, EMC36, ME202BB, NL2020, and SMP02. When the original cell degrades and the laptop loses charge capacity, this is the direct swap.\u003c\/p\u003e\n\n  \u003cul class=\"bpw-desc-bullets\"\u003e\n    \u003cli\u003e\n\u003cstrong\u003eApollo and MegaBook 911 compatibility:\u003c\/strong\u003e\n    Both models run the same 10.8V battery rail and use an identical connector housing and BMS handshake protocol. One cell fits both without adapter or modification.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003eBench tested on actual hardware:\u003c\/strong\u003e\n    We cycled this cell through charge, full load discharge, and BMS communication checks. The protection circuit responded correctly to over-charge and over-discharge thresholds, and the BIOS read the battery as present and healthy after the learn cycle completed.\u003c\/li\u003e\n\n    \u003cli\u003e\n\u003cstrong\u003ePost-install calibration on the Apollo:\u003c\/strong\u003e\n    After fitting this cell, run one full discharge to hibernate cutoff, then charge uninterrupted to 100%. This resets the BIOS battery learn cycle and clears the inaccurate health warning that appears after every cell swap on the Apollo platform.\u003c\/li\u003e\n  \u003c\/ul\u003e\n\n  \u003chr class=\"bpw-desc-divider\"\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eBIOS reporting battery health as poor after fitting the new cell\u003c\/h3\u003e\n\n  \u003cp class=\"bpw-desc-p\"\u003eThe Apollo's BIOS reads EEPROM data written by the original cell. When a new cell is installed, that stored data no longer matches the actual cell chemistry, and the system flags it as degraded or unknown. This is a firmware state, not a fault with the replacement. Run one full discharge-to-hibernate cycle followed by an uninterrupted charge to 100%. After two to three cycles, the BIOS recalibrates and the health status clears.\u003c\/p\u003e\n\n  \u003ch3 class=\"bpw-desc-h3\"\u003eLaptop shuts down at 20–30% charge shown on screen\u003c\/h3\u003e\n  \u003cp class=\"bpw-desc-p\"\u003eThis happens when the fuel gauge IC is still calibrated to the old, degraded cell's voltage curve. The new cell hits a voltage cliff under combined CPU and display load that the fuel gauge misreads as near-empty. The laptop cuts power to protect itself based on a wrong reference point. Run three full discharge-to-hibernate then full-charge cycles — by the third cycle, the fuel gauge IC resets its reference and the shutdowns stop. Verify the cell is reading above 10.8V at rest after charging.\u003c\/p\u003e\n\u003c\/div\u003e","brand":"BatteryWeb","offers":[{"title":"Warranty 1 Year","offer_id":43410838028378,"sku":"BWCS-SP500HB-1","price":88.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 2 Year","offer_id":43410838061146,"sku":"BWCS-SP500HB-2","price":103.99,"currency_code":"USD","in_stock":true},{"title":"Warranty 3 Year","offer_id":43410838093914,"sku":"BWCS-SP500HB-3","price":114.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0674\/4775\/0746\/files\/BW-CS-SP500HB-1.webp?v=1779581321","url":"https:\/\/batteryweb.com\/products\/megaimage-apollo-replacement-battery-108v-6600mah-li-ion","provider":"BatteryWeb","version":"1.0","type":"link"}
